30<H2>Description</H2>
31<p>The PMIC library maintains an internal buffer for audio data obtained from the Wii Speak.</p>
32
33<p>This function is used to check whether an overwrite has occurred in the buffer for internal audio data.</p>
34
35<p>The size of the buffer for audio data differs according to the method for initializing the library. If the library was initialized using the <code>PMICInit</code> function, the size of the audio data buffer is 48 ms (or approximately 70 ms for a sampling rate of 16 kHz or 11 kHz, or 96 ms for 8 kHz). When the library is initialized using the <code>PMICInitEx</code> function, the buffer size is specified by an argument.</p>
36
37<p>This function can be called regardless of the state of the Wii Speak (such as before it is open or while it is stopped or operating). </p>
